16. Mortal Enemies…Or Not
Khigh Dhiegh played McGarrett’s ultimate enemy, Wo Fat. He wasn’t on-screen with the series’ main character as often as you might think, though. He and Jack Lord only appeared onscreen together three times.
15. Jack Lord Was A U.S. Veteran
Jack Lord played Detective Steve McGarrett in Hawaii Five-O. Before being cast, he worked as a car-salesman, starred in Broadway, and was an actual Vietnam War Veteran. These experiences helped shape how he played his role.
